US Supreme Court takes on Womens' Suffrage
The 19th Amendment, which gave women the right to vote, was passed by Congress and sent to the states for ratification in June 1919. Although it had been approved by the required 36 (of 48) states by August 1920, Maryland still refused to allow women to register. After two lower courts had ruled against Maryland, the case--Leser v. Garnett--was sent to the US Supreme Court and argued on January 24-25, 1922.
The unanimous decision, which was handed down on February 27, 1922, agreed with the lower courts and upheld the Constitutionality of the 19th Amendment.
